It's not got a lot to do with the job. It's got a great deal to do with football fans' perception of the job. Does he look bothered? Is he shouting and pointing a finger? Does he celebrate when we score and look furious when the other lot get one back?it remains a mystery why football managers believe the touchline is the place to be, while rugby’s elite are generally high up in the stadium where they can spot patterns of play and, thus, actually do their job.
Top football isn't a sport anymore. It's a drama and the leading actors are the managers. The supporting characters, the players, are very often mild-mannered southern Europeans with limited English who are passing through on their way to a slightly better position in a warmer climate.
Only managers like Wenger, Moyes and Mourinho seem to have some skin in the game. Their pride's at stake. We see triumph and disaster written all over their faces. There's no way in the world TV would give that up and so the football authorities will keep on giving them it. Bad behaviour's part of the game, at every level. We wouldn't have it any other way.
